Abstract

The contribution of the $R$ -parity violating minimal supersymmetric standard model at the one-loop level to the ${}^{199}{Hg}$ atomic electric dipole moment through $P$ , $C P$ -odd electron-nucleon ( $e - N$ ) interaction is calculated. We show that the current experimental data of the ${}^{199}{Hg}$ electric dipole moment give tighter constraints on some of the imaginary parts of $R$ -parity violating coupling than those currently known. We add also the analysis of the $P$ , $C P$ -odd 4-quark interaction generated by $R$ -parity violating interactions at the one-loop level, and discuss the possibility to constrain them in future experiments.
